9 Cla.

This invention relates to improvements in coating, sizing and finishing compositions and more particularly to an improved permanent coating composition, used in the treatment of textile ma- 5 terials.

A particular object of this invention is the provision of the improved coating composition for the treatment of textile fabrics which will make such fabrics resistant to washing and to drycleaning, which will impart added strength to the fabrics and which will also impart certain waterproofing qualities to said materials.

Another object of the invention is the provision of an improved coating composition and process for producing same in situ on the fibre, which is especially applicable to delicate woven and knitted fabrics.

My improved coating composition is made in the following manner:

I provide a 5% water solution of hexamethylenetetramine, in which the fabric to be treated is first dipped at room temperatures, being immersed for approximately five minutes in said solution, the excess of the solution being then re- Clear glue or gelafine 20 it being-understood, that suflicient water is used dicated. These proportions are by weight.

10 parts of this parafiin emulsion are' then mixed with 90 parts of water, and the fabric which has been submitted to the hexamethylene-tetramine treatment is then immersed in the above mentioned paraflin emulsion at a temperature of from 80 to 90 F.

This immersion continues for about ten minutes, then the excess of the emulsion is drained off, and the goods are dried, preferably by running them over hot cans or driers, or in the case of hosiery, by subjecting same to drying over the customary metal forms. 7

The temperature during the drying operation should be from between 225 to 250 F.

By the use of the above steps a very light finish is produced, particularly suitable for silk goods.

For heavier materials such as cotton, the proportion of the ingredients can be doubled and a more heavy coating or is obtained.

moved from the fabric without drying the same.

to dissolve the percentage of glue or gelatine in- It will also be noted that other waxes can be used instead of paraffin, and other aluminum salts, such as aluminum acetate, can be used instead of the aluminum formate.

It is also apparent that other changes may be 5 made in the aforesaid formula, in the amount of ingredients used and in the substitution of other ingredients for the specific ingredients here mentioned, without departing from the spirit of my invention.

What I claim is:

1. A process of producing a permanent coating on a textile fabric by immersing same in a solution of hexamethylenetetramine and then subjecting the wet fabric to the action of an emulsion containing paramn, an aluminum salt and gelatine.

2. A process of producing a permanent coating on a textile fabric by immersing same in a solution of hexamethylenetetramine and then subjecting the wet fabric to the action of an emulsion containing parafiin, an organic aluminum salt, gelatine and glycerine.

3. A process of producing a permanent coating on a textile fabric'by saturating it in a solution of hexamethylenetetramine and then treating the wet fabric with an emulsion containing an organic salt of aluminum and gelatine.

4. A process of producing a permanent coating on a textile fabric by saturating it with a hexamethylenetetramine solution and then treating the wet fabric with a wax emulsion which contains a salt of aluminum formate, glycerine and glue.

5. A process of producing a permanent coating on a textile fabric by saturating it with a hexa-- methylenetetramine solution and then treating the wet fabric with a wax emulsion containing aluminum formate, glycerine and glue, and then drying the fabric at a temperature between 225 40 and 250 F.

6. A process of producing a permanent coating or sizing upon a fabric by saturating it with a solution of hexamethylenetetramine, then treating the wet fabric with an emulsion containing paraffin, aluminum formate, glycerine and glue, and then treating the fabric at a relatively high temperature.

7. A process of producing a permanent coating or sizing upon the fabric by saturating it with a solution of hexamethylenetetramine, then treating the wet fabric with an emulsion containing paraflin, aluminum formate, glycerine and glue, and then treating the fabric at a temperature of from 225 to 250 1!.

8. A method of waterproofing material which consists in applying to the material an aqueous solution of a substance which can react with gelatin so as to render the gelatin substantially insoluble in water so that said material takes up the solution, and then applying to the wet material an aqueous emulsion which contains gelatin and a water-proofing agent so that the surface of the wet material takes up a coating of said emulsion, and then drying the material.

9. A method according to claim 8 in which the substance is hexamethylenetetramine.
